The Blue Whale Challenge is an alleged suicide game that began in Russia, and is potentially spreading to areas such as the UK and France.

The game targets young pre-teen and teenaged children, requiring participants to complete daily tasks over the span of 50 days. The tasks include watching horror movies or waking up at abnormal hours in the night, and gradually grows more extreme, asking participants to commit acts of self-harm, before ultimately asking them to commit suicide on the 50th day in order to "win" the game.

RT, a Russian news organization, reported on the game in May 2016, allegedly linking it to "130 teen suicides in Russia."
